    APPLICATIONS:Regulationofinletpressuretogascompressors

    詳細介紹

    APPLICATIONS:
    Regulation of inlet pressure to gas compressors. Control of supply or distribution system pressures. Regulation of down stream pressure where it is desired that no gas be vented.
    ? Inside Buildings
    ? In Populated Areas
    ? Emissions Regulated Areas
    ? Sour or Poisonous Gas Systems
    PRESSURE RANGE:
    Upstream: 10 psig to 300 psig
    Downstream: 3 psig to 280 psig
    Minimum differential: 3 psi



    OPERATION:
    The Pilot assembly and Motor Valve Stem Assembly (Crosshatched) are the only moving units in the regulator. The PILOT PLUG consists of two stainless balls rigidly connected together. Upstream Pressure (Red) is the supply pressure to the pilot and is also in constant communication with the top side of the MOTOR VALVE DIAPHRAGM. The area of the MOTOR VALVE DIAPHRAGM is twice the area of the motor valve seat, assuring a positive shut-off.
    The lower seat for the PILOT PLUG is the Motor Valve Diaphragm Pressure inlet (Red to Yellow). The upper seat for the PILOT PLUG is the pressure vent (Yellow to Blue). The PILOT SPRING loads the upper side of the Pilot Assembly and is opposed on the underneath side by controlled Downstream Pressure (Blue).
    Assume the PILOT SPRING is compressed with the ADJUSTING SCREW for a desired Downstream Pressure setting. With Downstream Pressure (Blue) too low, the PILOT SPRING forces the Pilot Assembly downward to close the upper seat (Yellow to Blue) and open the lower seat (Red to Yellow).
    This lets full Upstream Pressure (Red), if necessary, load the underneath side of the MOTOR VALVE DIAPHRAGM to balance the pressure on the top side. Upstream Pressure (Red) acting under the motor valve seat, opens the valve. As Downstream Pressure (Blue) increases to the set pressure, the Pilot Assembly assumes a position in which both seats of the PILOT PLUG are closed.
    Should Downstream Pressure (Blue) rise above the set pressure, the Pilot Assembly moves upward against the PILOT SPRING to open the pressure vent (Yellow to Blue). Motor Valve Diaphragm Pressure (Yellow) decreases to reposition the Motor Valve Stem Assembly.
    The intermittent bleed pilot, three-way valve action of the PILOT PLUG against its seat adjusts the Motor Valve Diaphragm Pressure (Yellow), repositioning the Motor Valve Stem Assembly to accommodate any rate of flow.
    The rapid but stable repositioning produces a true throttling action.
